Core Frequency = CPU Bus Clock * 4 * CPU Ratio
PCI Clock = CPU Bus Clock / Clock Ratio
AGP Clock = PCI Clock x 2

Warning: Intel
®
850E chipset supports maximum 400MHz
(100MHz*4) / 533MHz (133MHz*4) system bus and 66MHz AGP
clock, higher clock setting may cause serious system damage.

Note: Since the latest processor,
Northwood, would detect the clock ratio
automatically, you may not be able to
adjust the clock ratio in BIOS manually.
